However, with the demand to more high-quality acoustical behavior, existing sound film wrinkle pattern structure can no longer meet
The requirement of sound film stationary vibration, sound film still will appear the case where distortion is waved and is distorted when vibrating, can not obtain preferable sound
Learn performance.
Therefore, it is necessary to provide a kind of new sound film to solve the above problems.
【Utility model content】
The purpose of this utility model be to provide it is a kind of can be effectively improved sound film vibration when distortion wave and be distorted, improve
The sound film of acoustical behavior.
To achieve the above object, the utility model provides a kind of sound film comprising centrally located top dome portion and
Around the ring portion of top dome portion setting, the ring portion is equipped with multiple first folds, first pleat in its corner location
Wrinkle extends along the direction in the outside for being directed toward the ring portion by the inside in the ring portion, and the ring portion is additionally provided with same across it
At least one second fold of the first fold of each of one corner location, second fold are turned along corner location where it
Angle extending direction extends.
As an improvement the protrusion direction of first fold is identical with the protrusion direction of second fold, it is described
The protrusion direction of first fold is identical as the protrusion direction in ring portion.
As an improvement the protrusion direction of first fold is identical with the protrusion direction of second fold, it is described
The protrusion direction of first fold is opposite with the protrusion direction in ring portion.
As an improvement the protrusion direction of first fold and the protrusion direction of second fold are on the contrary, described
The protrusion direction of first fold is identical as the protrusion direction in ring portion.
As an improvement the protrusion direction of first fold and the protrusion direction of second fold are on the contrary, described
The protrusion direction of second fold is identical as the protrusion direction in ring portion.
The utility model has the beneficial effects that：The sound film of the utility model passes through the corner location setting the in its ring portion
One fold and the second fold, distortion when can be effectively improved the vibration of sound film are waved and are distorted, and acoustical behavior is improved.
【Description of the drawings】
Fig. 1 is the stereoscopic schematic diagram of the sound film of the utility model；
Fig. 2 is the schematic top plan view of the sound film of the utility model.
【Specific implementation mode】
The utility model is described in further detail below by specific implementation mode combination attached drawing, so as to more preferably
Ground understands the advantages of the embodiment of the utility model and its various aspects.Below in an example, embodiment party in detail below is provided
The purpose of formula is easy for becoming apparent from thorough explanation to the content of the utility model, rather than limitations of the present invention.
As depicted in figs. 1 and 2, it is a kind of sound film 10 provided by the utility model comprising centrally located top dome
Portion 11, the ring portion 13 being arranged around top dome portion 11 and the fixed part 15 extended from ring portion 13.
Wherein, ring portion 13 is equipped with multiple first folds 131 in its corner location, and the first fold 131 is along by ring portion 13
The direction in the inside outside of being directed toward ring portion 13 extend；Ring portion 13 is additionally provided with across each of its same corner location
At least one second fold 133 of one fold 131, the second fold 133 extend along the turning extending direction of corner location where it；
Fixed part 15 is used for and the components secure bonds such as such as frame.
In the present embodiment, ring portion 13 is upward protrusion, and the first fold 131 and the second fold 133 are from ring
The downward protrusion in portion 13 can also be that ring portion 13 is downward protrusion, the first fold 131 and the in other embodiments
Two folds 133 are from the upward protrusion in ring portion 13, it can be understood as the protrusion direction of the first fold 131 and the second fold 133
Protrusion direction it is identical, the protrusion direction of the first fold 131 is opposite with the protrusion direction in ring portion 13；
It is, of course, also possible to be ring portion 13 be upward protrusion, the first fold 131 and the second fold 133 are from ring portion
13 upward protrusions；Or ring portion 13 is downward protrusion, the first fold 131 and the second fold 133 are downward from ring portion 13
Protrusion, it can be understood as the protrusion direction of the first fold 131 is identical with the protrusion direction of the second fold 133, the first fold 131
Protrusion direction it is identical as the protrusion direction in ring portion 13；
It is, of course, also possible to be ring portion 13 be upward protrusion, the first fold 131 be from the upward protrusion in ring portion 13,
Second fold 133 is from the downward protrusion in ring portion 13；Or ring portion 13 is downward protrusion, the first fold 131 is from ring
